Sparse domination and $L^{p} \to L^{q}$ estimates for maximal functions associated with curvature

Wenjuan Li, Huiju Wang, Yujia Zhai

In this paper, we study maximal functions along some finite type curves and hypersurfaces. In particular, various impacts of non-isotropic dilations are considered. Firstly, we pro…

Biparameter $BMO$ under the action of a rotation

Frédéric Bernicot, Yujia Zhai

In this work, we aim to study the action of composing by a rotation on the biparameter $BMO$ space in $R^{2}$ . This $BMO$ space is not preserved by a rotation…
